Two people were killed Sunday when a car veered off a Buckeye road and landed in a nearby canal, according to the Maricopa County Sheriff's Office .

The crash happened just after 1 p.m. near 307th Avenue and Lower River Road, said Sgt. Calbert Gillett, an MCSO spokesman. The driver was heading west on Lower River Road when he apparently lost control of the vehicle, Gillett said.

He said both the driver, who was thrown from the car, and his passenger were pronounced dead at the scene.

It was unclear whether impairment was a factor in the crash, which remained under investigation Sunday.
